Profile
Scientific name:	Atrophaneura horishana (Matsumura)

Features:	The Highland red-bellied swallowtail butterfly is a fairly large-sized swallowtail with a wingspan stretching 9-12cm and no tail. Males have black wings suffused with a lustrous, bluish-black, silky, velvety substance; upper hind wings with folds on their inner margins that look like white, fluffy insides; and lower hind wings that have seven, large, black but slightly peachy spots. Females have black wings too, but with yellowish-black coloring along their veins, and the seven black spots on their lower hind wings are less peachy than males.
Behavior:	The larvae of Highland red-bellied swallowtail butterflies feed on the leaves of the Aristolochia shimadai Hayata; adults, which emerge between July and September, are slow fliers and prefer to sip the honeydew of the Sambucus formosana.
Habitat:	Highland red-bellied swallowtail butterflies are endemic to Taiwan and distributed mainly in mountainous regions at 1000-2500m elevations. They are commonly seen on Lishan and Wuling, as well as by the Bi-lu Stream and along the upper reaches of the Choshui Stream. The southernmost area in which they can be found is in Kaohsiung County's Liu-Gui.
